Chemical Resistant Manual Stainless Steel Gate Valve Female Thread
Gate valves are designed for fully open or fully closed service.
They are installed in pipelines as isolating valves and should not
be used as control or regulating valves. Operation of a gate valve
is performed doing an either clockwise to close (CTC) or clockwise
to open (CTO) rotating motion of the stem. When operating the valve
stem, the gate moves up- or downwards on the threaded part of the
Gate valves are often used when minimum pressure loss and a free
bore is needed. When fully open, a typical gate valve has no
obstruction in the flow path resulting in a very low pressure loss,
and this design makes it possible to use a pipe-cleaning pig. A
gate valve is a multiturn valve meaning that the operation of the
valve is done by means of a threaded stem. As the valve has to turn
multiple times to go from open to closed position, the slow
operation also prevents water hammer effects.
